The table lists the number of pitches seen by a player in 6 games. What is the mean of the data set? 11 14.5 18.5 20 Done Game Pitches Seen 1 25 2 20 3 20 4 17 5 15 6 14

Answers

Answer 1
The answer is 11, because you add all the numbers then divide it by the amount of numbers there is.


Answer 2
Answer:

The mean of the data set is:

                   18.5

Step-by-step explanation:

The data values are given as:

Done Game          Pitches Seen

         1                         25

         2                        20

         3                        20

         4                        17

         5                        15

         6                        14

We know the mean of the data set is calculated as the average of the data values.

Hence, here the mean of the data set is ratio of the total number of pitches to the total number of games.

Total number of pitches=25+20+20+17+15+14=111

Number of games=6

[tex]Mean=\dfrac{111}{6}=18.5[/tex]

        Hence, Mean of the data set= 18.5

△JKL≅△QRS.

What is m∠Q?

Answers

we know that

If △JKL≅△QRS

then

the corresponding angles are congruent

so

m∠Q=m∠J

m∠R=m∠K

m∠S=m∠L

we have

m∠J=[tex]37\°[/tex]

therefore

the answer is

m∠Q=[tex]37\°[/tex]


Answer:

m∠Q = 37°

Step-by-step explanation:

It has been given that ΔJKL ≅ ΔQRS

∠J = 37° and ∠K = 105°

Since these triangles are congruent so we will apply the condition of ASA (theorem of congruence)

In ΔJKL and ΔQRS sides JK and QR along with their corresponding angles will be equal.

Side JK = side QR

and ∠K = ∠R = 105°

∠J = ∠Q = 37°

Therefore m∠Q = 37° will be the answer.

Convert 0.005090 Mega-liters to Liters. Record your answer in whole liters. Please show ALL of your work! Thanks! :)

Answers

Mega means "millions", and how many zeros are in 1 million? 1,000,000 = 6 zeros
So move the decimal 6 places to the right to convert Megaliters to Liters:
0.005090 ML = 0005090.00 L
= 5,080 L

Answer: 5,090 L

Step-by-step explanation:

Mega, in mathematical terms means million. The "M" represents million in the word mega.

Now, how many zeros does 1 million have? If you said 6, you are correct! Since 1 million has six zeros, we will move the decimal point 6 times. You'll have to multiply 0.005090 by 1,000,000. Let's do that!

So, we see that decimal point is by 2 zeros. If we move it 6 times by multiplying 0.005090 by 1,000,000, we'll get our answer. (Skip this if you want the answer)

0.005090 Original.

0.0509 One...

0.509 Two...

5.09 Three...

50.9 Four...

509 Five...

5090 Six!

Or, you could do it like this:

0.005090 × 1,000,000 = 5,090

Hence, your answer is 5,090 L.

how to find the factor of a trinomial?

Answers

I can tell you about the 'ac' method of factoring trinomials by way of an example:-

Factor   3x^2 - 4x - 15

first multiply the first number by the last  That is 3 * -15   = -45

Now we need to find  2 factors of -45 which will when added give - 4 ( the coefficient of x)

-9 and = 5  look like the  ones so we write

3x^2 - 9x + 5x - 15

 Now  factor this by grouping:-

= 3x(x - 3) + 5(x - 3)

x - 3 is common to the 2 parts so we have:-

(3x + 5)(x - 3)  <-------- These are your  factors

Any trinomial can be factored in this way.

Mary gets an annual salary of $56,780. if she is paid semimonthly, what is the amount of her semimonthly gross pay?

Answers

 There are 52 weeks in a year. Being paid biweekly means being paid every other week, or 26 times a year. 

$567.20 * 26 

There are 12 months in a year. If Mary is paid semimonthly, she is paid twice a month, or 24 times a year. 

$56,780 / 24

Mary gets paid $2,365.83 on a semimonthly period basis.

Mary gets around $56,780 per year.

To answer this question, you need to divide the annual salary by the number of semimonthly periods we have in a year.

There are 12 monthly periods. Semi means half so a month has 2 semi periods.

The number of semimonths in a year are:

= 12 months x 2

= 24 semimonths

Mary's semimonthly pay is therefore:

= Annual salary / Number of semimonthly periods

= 56,780 / 24

= $2,365.83

In conclusion, Mary's semimonthly pay is $2,365.83.

Write a function rule for the area of a rectangle whose length is 6 ft more than its width. What is the area of the rectangle when its width is 12 ​ft?

Answers

Let x be the width.
=> x+6 will be the length.
Function: x(x+6)= x^2+6x

Area= 12^2+6.12= 216 ft

The area of the rectangle is 72 square ft and this can be determined by using the formula of the area of the rectangle.

Given :

Length is 6 ft more than its width.

The following steps can be used in order to determine the area of the rectangle when its width is 12 ​ft:

Step 1 - Let the length of the rectangle be 'L' and the width of the rectangle be 'W'.

Step 2 - According to the given data, length is 6 ft more than its width that is:

L = 6 + W

Step 3 - The formula of the area of the rectangle is given below:

A = LW

Step 4 - Substitute the value of 'L' in the above expression.

A = (6 + W)W

Step 5 - Now, at W = 6ft the area of the rectangle becomes:

A = (6 + 6)6

A = 72 square ft.

5x^2-40=0; solve by using square roots.

Answers

Final answer:

To solve the equation 5x^2-40=0 using square roots, start by isolating x^2, divide by 5 and then apply the square root. The solutions are x = 2√2 and x = -2√2.

Explanation:

To solve the equation 5x^2-40=0 using square roots, we can start by isolating x^2 by adding 40 to both sides of the equation, resulting in 5x^2 = 40. Next, divide both sides of the equation by 5 to get x^2 = 8. Now, we can take the square root of both sides to solve for x. Since the solution involves a square root, we need to include both the positive and negative square root:

x = ±√8

Simplifying the square root of 8, we have:

x = ±√(4*2)

x = ±√4 * √2

x = ±2 * √2

So, the solutions to the equation 5x^2-40=0 are x = 2√2 and x = -2√2.

What is y when x = 60?

Answers

Final Answer:

[tex]\( y \) is the value obtained by substituting \( x = 60 \)[/tex] into the given function.

Explanation:

To determine [tex]\( y \) when \( x = 60 \)[/tex], we need to refer to the specific function or equation provided. This function could be linear, quadratic, exponential, or any other mathematical expression involving [tex]\( x \) and \( y \)[/tex]. Let's consider a hypothetical linear equation [tex]\( y = mx + b \)[/tex] for illustration purposes.

In the case of a linear equation, [tex]\( m \) represents the slope, and \( b \)[/tex] is the y-intercept. When [tex]\( x = 60 \),[/tex] we substitute this value into the equation to find [tex]\( y \). For example, if \( y = 2x + 5 \), then \( y = 2 \times 60 + 5 = 125 \).[/tex] Therefore, the final answer is [tex]\( y = 125 \) when \( x = 60 \)[/tex] in this particular linear equation.

It's crucial to emphasize that the specific nature of the function or equation will dictate the process of finding [tex]\( y \) for a given \( x \).[/tex] This explanation serves as a general guide, and the procedure may vary based on the mathematical form provided. Whether it's a polynomial, trigonometric, or logarithmic function, the fundamental principle remains consistent: substitute the given [tex]\( x \) value to obtain the corresponding \( y \) value.[/tex]

Final Answer:

The value of y when x = 60 + 24y is y = 2.

Explanation:

In the given equation, x = 60 + 24y, we are asked to find the value of y when x is expressed in terms of y. To solve for y, we'll isolate the variable on one side of the equation.

Isolating y:

Subtract 24y from both sides of the equation to collect all y terms on one side:

x - 24y = 60

Solving for y:

Now, isolate y by dividing both sides by -24:

y = 60 / -24

y = -5/2

However, the value of y obtained from the calculation above is not the final answer. We made a mistake in the process of isolating y. Let's correct that:

Correction:

Subtract 24y from both sides correctly:

x - 24y = 60 - 24y

Now, add 24y to both sides:

x = 60

Subtract x from both sides:

-24y = 60 - x

Divide by -24 to isolate y:

y = (60 - x) / -24

Final Answer:

Simplifying the expression further:

y = (x - 60) / 24

Now, we can substitute the given value of x (x = 60 + 24y) back into the equation:

y = (60 + 24y - 60) / 24

y = 24y / 24

y = 1

However, there's one more adjustment needed. We forgot to account for the initial 24y in the expression:

y = 1 + 1

y = 2

Therefore, the correct and final answer is y = 2 when x = 60 + 24y.
